1. A method for processing user plane data by a terminal, the method comprising:
- receiving additional configuration information to further configure a wireless local area network (WLAN) carrier that uses an unlicensed frequency band through an aggregation entity;
receiving downlink user plane data through the WLAN carrier according to the additional configuration information; and
transmitting uplink user plane data by using at least one of the WLAN carrier and a base station carrier as a transfer path of the uplink user plane data according to the additional configuration information,wherein the additional configuration information includes information indicating an uplink data transfer path type to be separately applied for each radio bearer, andwherein the aggregation entity configures an IPSec tunnel between the based station and the terminal for transmitting and receiving the user plane data through the WLAN carrier.
